What is the major difference between fn:empty and create functions in graphical data mapping node in message broker v8.
while migrating my message map from v6 to v8 i came to know there were number of empty elements, to handle these empty elements we have used msgmap:empty-element function in v6.1, so in order to handle these elements in V8, we have used mainly two functions i.e. fn:empty and create.
I came to know that both fn:empty, but create functions does the same functionality. but i didn't figure out which one is better in performance wise.
when i used the fn:empty the default value is ' '. If if remove the default value in fn:empty i am getting a run time error as "empty" is not a function.
please give me an advise which one is better as performance wise. |

Maybe there is a third way. Instead of dealing with empty elements in your transformation logic, can you use the facilities of XML Schema ( if the output is XML ) or DFDL ( if not XML ) to insert the default values automatically? Apologies if you already considered that - but a migration project is sometimes a good opportunity to fix old design issues.

But in my message map node i am using multiple times those attributes, some times with values and some times with default values.
so i can not use default values in schema. |
